1. Some Project Ideas
Literature review of particular subjects – what is new since “Applied Hydrology” was originally published?
What are the key papers in this field since 1988?
Flood hydrology modeling and flood mapping
Effect of flood control dams in Sanderson, Texas
Unsteady flow modeling using HEC-RAS

2. NRC Studies on Flood Mapping
Elevation Data for Floodplain Mapping (2007)
Examines elevation and image information supporting flood mapping and recommends coast to coast LIDAR for the nation
Mapping the Zone: Improving Flood Map Accuracy
Case studies of the uncertainty in hydrology, hydraulics and terrain data on flood map accuracy

3. Adjusted goal: 92% of population and 65% of land area will have a modernized map
21% of population has maps meeting the floodplain boundary standard and engineering study standard 3

4. Map Modernization in Texas

5. Sanderson, Texas
County Seat of Terrell County

6. Flood Mapping in Sanderson
There is an existing paper flood map
There was a severe flood in Sanderson on June 11, 1967 in which 28 people died
The USDA Soil Conservation Service built several flood control dams upstream of Sanderson during the 1980’s
Sanderson needs a Digital Flood Insurance Rate Map to reflect the existence of these flood control dams
